Finasteride ED Paranoia (from Reddit)

I recently started taking finasteride(3 weeks ago) and put a post up about my fears of gynecomastia. I can confidently say thats not happening to me as my paranoia thought ( after doing some blood tests and consulting my doc). I was extremely paranoid for that too. Luckily its pretty easy to prove wrong. However, i noticed my attention started to go towards my performance with mini me (penis). I never complained about my performance for 2 weeks. Only after i stopped paying attention to my chest did this kick in. I masturbated 6 times in the last 32 hours to prove myself that i dont have ED. Each time i was able to orgasm. I noticed that it wouldn’t get fully erect when i was thinking about finasteride and its side effects. After the second go, it got more difficult to get it up ( which i expect has to do with round 1&2) I never focused on my performance prior to this so i cant really compare. So right now im not sure if i have ED or just paranoid. Essentially is there anyway i can prove that i dont have ED or do? I stopped finasteride for now until i am sure. Im aware that the percent of placebo reporting ED and finasteride ED are really close percentages. Btw if you need a more info about my performance to make a decision, please ask me. Im not shy. Morning wood is a good sign but i haven’t seen that so much since i started smoking weed b4 bed (been doing that for about a year). So what are key signs that would mean you have ED?
